The plot involves an asteroid heading to earth, Keira Knightley and Carell on a journey to find Carell’s lost love before the world is destroyed, and a waitress they meet who’s tweaked out on ecstasy – which is where Jacobs comes in. Hopefully she won’t do the real drug while filming, because the “Fresh Prince” handshake is tricky to do on E. You know isn’t tricky, though? Getting a nice backrub.
